Keystone Butterfly Valve <strong>Figure</strong> <strong>990</strong><strong>The</strong> <strong>Figure</strong> <strong>990</strong> <strong>butterfly</strong> <strong>valve</strong> <strong>has</strong> a <strong>split</strong>, <strong>wafertype</strong> <strong>body</strong>, <strong>features</strong> a onepiece disc stem and field replaceable seat.<strong>The</strong> range of available materials makes these <strong>valve</strong>s suitable for a widevariety of applications.FeaturesGeneral application<strong>The</strong> figure <strong>990</strong>-102/003 is the ideal <strong>valve</strong> for usein the food and beverage industries.<strong>The</strong> figure <strong>990</strong>-007 is PTFE lined for usein semi-aggressive chemical industries.Max pressure 7 bar.<strong>The</strong> figure <strong>990</strong>-002 is rubber lined for use in theprocess industries. Max pressure 7 bar.Warning!Not for use on unstable gasses.Not for end of line use.Technical dataPressure (bar): 10Temperature (°C): -10 to +150Sizes (mm): 25-300Flangeaccommodation: PN 10/16ANSI 150BST’E’• Factory testing of every <strong>valve</strong> at full ratingensures 100% bubble-tight shut-off.• Standardized actuator flange for easyoperator interchangeability and mount directto Keystone Range of actuators.• One-piece wafer-thin disc-stem provides highstrength and absolutely positive disc controland gives the very minimum obstruction toflow. Its crevice free surface makes it idealfor hygienic duty.• Primary seal formed by the seat/shaft/hubcontact exceeds the pressure rating of the<strong>valve</strong>. Body is totally isolated from the flowingmedium.• Secondary shaft seal is suitable for pressureand vacuum is self adjusting.• Patented dove-tail seat requires no bonding.Makes seat replacement simple and fast.Extra heavy edge section resists tearing.• Hub seal is provided by preloaded contactbetween flatted seat surface and roundedpolished disc-hub area for positive sealing atall disc positions.• Molded-in O-ring provides positive flangesealing and eliminates the need for gaskets.• Heavy duty top bushing absorbs side thrustloads. Self-adjusting sealing for bothdirections is also suitable for vacuum.www.pentair.com/<strong>valve</strong>s© 2012 Pentair Inc. All Rights Reserved.EBPJD-0260-EN-1401
